COMBINED HOOK AND nour Andrew H. Hatchette, Cleveland, Ohio ApplicationMarch 21, 1939, Serial No. 263,269

4 Claims. (01. 292 -105) This invention aims to provide a novel meanswhereby a hook may be held securely but releasably engaged with akeeper, it being a matter of common knowledge that a person desiring tocrack his way into a house, generally can release a screen door hookfrom its keeper by shaking or pulling on the door, or by insertingathin, hook-lifting instrument between the doorand the door frame. I

Fig. l is an elevation wherein the bolt is retracted, Fig. 2 is anelevation wherein the bolt is advanced, Fig. 3 is an elevation showing amodification, the bolt being advanced, and Fig. 4 is an enlargedelevation 01 the spiral body of the hook, the showing of Fig. 4applying, to either form oi. the invention.

The numeral I marks either a door or door jamb, carrying a screw-eye orother keeper 2. The numeral 3 designates a hook, made or a piece ofrigid rod stock of common cross sectional diameter throughout itslength, the hook includin a longitudinal shank 4 having at one end aneye I whereby the hook is pivotally connected to a screw eye or otheranchor 8, adapted to be mounted (v 25 on either a door frame or a door.

the. hook 3 extends through the keeper 2 and has The bill of a side seat8.

The intermediate portion of the shank 4 is formed into a spiral body 9,the terminal convolutions ID of which are closer together than are theremainingorintermediate convolutions. A bolt II is closely guided forright line reciprocation in the body 9 but is rotatable therein, thebolt having a lateral handle l2, movable between, and adapted to follow,the convolutions of the ody.

The operator lays hold 01' the handle-l2 and rotates the bolt II, thehandle follows the con-'- volutions of the body 9, the bolt is advanced,the working end or the bolt cooperates with the seat 8, and the bill Ioi'the hook cannot be disengaged from the keeper 2. When the handle I!reaches the less widely spaced convolutions l0 at the forward end of thebody I, it is pinched between them, and it will not be possible, byshaking the door, to cause the handle I! to swing down, follow theconvolutions of the body i and retract the bolt ll out of engagementwith the seat 8. The less widely spaced eonvolutions II at the rear endof the body 9 function in the same way, to hold the bolt ii retracted.

In Fig, 3, parts hereinbefore described have been designated by numeralsalready used, with thesuiiixc. Thebodylalsshorter'thanthe body 9, andthe bolt Ila has a shorter throw than the bolt II. Added security andstability in the bolt Ha are secured by mounting it in a dependingguiding eye l4, produced by looping and twisting the shank 411 onitself, the guiding eye being disposed close to the bill la. Securityispromoted, moreover, because the working end. of the bolt I la engagesnot only with the seat to, but underneath and in contact with the keeper2a, as well.

A smith or iron-master, who abides by what is claimed, may make changesin the precise structures shown, without departing in correspondingmeasure from the spirit of .the in v ention.

I claim: 4

'1. A two-piece retainer ior screen doors and similar closures,including a hook formed from rod stock and comprising a shank having abill, the shank being spirally disposed to form a body, I:

and a bolt mounted in transverse handle, extended outwardly between theconvolutions of the body and exposed there beyond for directmanipulation, the handle constituting means whereby-the bolt may berotated, 1

the handle following the convolutions, when the bolt is rotated, therebyto advance the bolt longitudinally, into cooperating relation withrespect to the hill.

2. A two-piece retainer for screen doors and similar closures,constructed as set forth in claim 1, and wherein the convolutions at oneend of the body are located more closely together than are the otherconvolutions, and so closely together as to pinch the handle and holdthe bolt releas ably against rotation and longitudinal movement.

' 3. A two-piece retainer -for screen doors and similar closures,constructed as set forth in claim 1, and wherein the convolutions whichare at the inner end of the body are located more closely together thanare the other convolutions, and so closely together as to pinch thehandle and hold the bolt releasably against rotation and 10 8 close totheblll, the bolt being slidable in the guiding-eye.
